COASTER.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed May 31, 1916. Serial No. 100,894.

To all whom it may concern:

Be it known that I, WALTER F. BAILEY, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Coasters, ofwhich the following is a specification.

This invention relates to a coaster and particularly pertains to a smallportable vehicle used bychildren for coastin upon grades and to conveythem from p ace to place.

It is an object of this invention to provide a light, portable vehicle uon which a person may stand and by whic he may be carried.

Another ob'ect is to provide treadle means whereby the device may be setin motion by the movement of the feet when it is not mov ing on a grade.

Another object is to provide means whereby the movement of the foottreadles will act.

to impel the vehicle in a forward direction irrespective of whichtreadle is moved.

It is another object to provide a propelling, mechanism in connectionwith the treadle members which will run idle and not interfere with theforward movement of the vehicle when the foot treadles are held againstmovement and thus allow the vehicle to coast when suflicient momentumhas been obtained.

It is an object of this invention to provide a simple clutch mechanismwhich is operated in connection with the foot treadles to rotate thedriving gear of the vehicle and which will run idle when the driving earis rotated by other forces than that of t e propelling mechanism.

Another Ob]BCt of this invention is to provide a suitable steering meanswhich also forms a substantial member for steadying the rider standingupon the vehicle.

Another object is to provide a simple power transmission member adaptedto connect the foot treadles with the driving clutch, said member beingsimple in design and not easily made inoperative.

It is a further object to provide a coaster which is substantial in itsconstruction and of few simply constructed movable parts which ma bereadil maintained in an operative con ition by t e ordinary youth.

Oth r o jec s w ll appear hereinafter.

The invention is illustrated in the accompanying drawings in which:

Figure 1 is a view in side elevation illustrating the device asassembled for use and showing the steering column as broken away for thesake of convenience.

Fig. 2 is a view in plan of the coaster as shown in Fig. l andillustrates the relation between the foot treadles and the powertransmission mechanism of the device.

Fig. 3 is a view in side elevation with parts shown in vertical sectionto illustrate the clutch arrangement of the rear axle.

F 1g. 4 is a view in vertical section through the power transmission andthe driving axle of the coaster as. seen on the line 4-4- of Fig. 3 andin the direction indicated by the arrows.

Referringto the drawings more particularly, 10 indicates a horizontallydisposed floor board beneath which is a running gear comprising a singlefront steering wheel 11 and a pair of oppositely arranged driving wheels12 and 13 positioned in a suitable manner, to be hereafter described,beneath the rear end of the floor board. The front steering wheel isprovided with a Wheel fork composed of a pair of vertically ext-endingfork members 14 and 15 which are secured to a steering post 16 by meansof suitable screws 17. The steering post 16 is here shown as constructedof wood and extending upwardly a considerable distance above the line ofthe floor 10. A pair of handle bars 18 are rigidly secured adjacent theupper terminating end of the steering column and provide means for thesteering wheel 11 to be turned upon its pivot pin 19 which is secured tothe steermg column by means of a U-shaped bracket 20. The bracket 20 hasbearing lugs 21 and 22 formed at its ends and in vertical relation toeach other. The pivot pin 19 secures the bracket and its steering gearto the floor board of the vehicle b means of a lower bracket member 23suite. 1 fastened to the floor board and an upper bracket andreinforcing member 24: which is secured over the top of a treadle pivotblock 25. The member 24 extends diagonally downward to the fioor boardwhere it is secured by a suitable bolt 26.

The treadle ivot block is secured by means of bolts 2 to the forward endof the floor 10 and extends upwardly in a vertical manner. A treadlepivot pin 28 is horizontally disposed and positloned through the upperend of the pivot block and is adapted'to engage the piv'otends 29 and 30of the treadlcs 31'and32 The pivot ends 29 and 30 are a part of trundleli'itliiu men bers 33 and 34 arcuutely lore-led in swee 'i' downwardlyand then continue ih oughout the feet of the rider, and allow him tostand' thereupon while operating and riding upon the coaster.

Reference being bad to Fig. 4 of the draw ing, it will be observed thatthe rear driving wheels 12 and 13 are mounted to rotate with the drivingaxle 4O suitably secured to the footboard 10 by means of a bearingmember41 provided with a pair of oppositely dis posed downwardly extendingaxle supports 42 and- 43. The bearing member 41 is mounted upon-thefoot-board by bolts 44. The axle 40 extends horizontally between therear wheels 12 and-Band is formed-shits outer ends withthreaded portions45 adapted to be engaged by suitable nuts which rigidly hold the wheelsagainst shoulders 46 of the-cylindrical axle ends 47 and48. The axleportions 47 and 48 extend to a point adjacent the center of the axlewhere a ratchet member 49 of an enlarged diameter is mounted. Theratchet member is formed with a series of longitudinally extending teethmember 50 which have a radial face and a tapering back leading to thelowermost edge of the tooth face adjacent. It will be noted that thestraight radial faces are'dis posed toward'the rear of the coaster asthey pass'aroundandover their axialpoiht. The ratchet member 49 is ofsufiicient'width to be partially'encompassed by the enlarged portionofapair of driving sleeves 51 and 52 which are adapted to bear upon thecylindrical axle portions 47 and 48 and rotate therearound. A pair ofpawls 53 and 54 are pivotally secured With'in'the enlarged portions ofeach ofthe sleeves and are adapted to normally abut against theradialfaces of the teth50 being there held by means of spring members 55. "It\vill'thus be seen that when either of the sleeves is rotated in thedimetion indicated by the arrow-a,theratchet teeth will be engaged andthe axle with its drivingwvheels' willbe rotated to move the vehicle ina forward'direction.

As a means of'transmittingtlie movement of the foot treadles 37 and 38to the rear axle andthere'by rotate it, an endless cable 56 has beenprovided which is suitably cla'i'nped' against'thc rear terminating endsof the treadle frames by clamping straps 57 and 58 which are held bybolts 59. Theendless cahlc'htj'is' protide dw'ith'a pair of horizontallydisposed grooi'e'd" idler pulleys (it) and til rotalubly mounted at theupper end :u'i d u'ilhin a U-shaped transmission case 31% which extendsvertically from the foot-board lt iind is tl'iere secured bymeansohboits (53'.

The 'en'dlesseable 56 is led dou'nwardly from the opposite outer sidesthe pulleys no and (31 and is ledaroundthe'sleeveidembers 51 and 52WlliClttlb rotatably mounted upon thedrivin 'axl'el' After having beenled aroundthesleetes a sufficient number-of turns to correspond in"circumferential. le'ngth to uietiea'dl movement, thembie is passedthroughclanlping bosses'dfi and'there held by'means of set screws 66.Anotlier portion of the "cable'is th'efi'led afour'i'd'the sleeye andupwardly over" a centrally dis osed idler wheat- 67.
